Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of …

Theory and Operation of Capacitors

Capacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it absorbs energy (current going in the negative side and out the positive side, like a resistor).

Technical

The PRIMARY purpose of the capacitor in a coil /points/capacitor circuit is to tune the circuit to RESONANCE. When this is achieved, the impedance of the circuit is at maximum and current flow is minimum. Current flow being minimum is where the points will have the longest life. Resonance peak is also dependent on frequency. RPM in this case.
